p it through the passage 12 which" vforms the initial introduction to andconneche present invention, -and has housingf -.:convcni n preferablyb p b then-PL I it is olovious that this housing may be formed: 7

At the top of the, housing'a chamber 15 18 i nozzles 17 depend a likenumber of chains" u 18, the chainsbeingof such relative lengths and proportions that .zber opposite the inlet 12 the chains substan: tially disappear and at the side of the'con at the side of the 'cham- (9O particularly at. Figure 1;

Withinthis housing a frame 19 secured by the'bolts QOL' a plurality of chains 21'are suspended on'an series or plane of chains being below the h er end of the upper J 1'00 the'inletconduit'12 and the upper endextending substantially to the inlet conduit 12 necessitates the passage of the smoke or products of combustion from the inlet passage 12 through the several chains 18 and 21 in passing from such inlet conduit 12 to the outlet port 22.

The chains 18 arekept continuously Wetted with a film of water which is supplied to the pipes 16 by means of an inflow pipe 23 from a pump 24. "The chains '18 being located directly above the chains 21, the water supplied to the chains 18 in addition to forming a film of water continuously uponthe exterior of such chains drips down to and upon thechains 21 where it also forms continuously a film of Water which finally drips downwardly into a funnel 25 located in the housing. Preferably this funnel is secured in the housing by means of a flange26 secured betweenthe sections 13 and 14 of the housing, but it is obvious that any other manner of securing the funnel in such housing will be within these-ope of thepresent invention.

Thefunnel 25 communicates by means ofa,

pipe 27, preferably, though not-necessarily tapered with a goose-neck 28' which discharges into a closedbox or receptacle 29.

This box or receptacle 29 communicates by means of a pipe 30 with the pump 24 so that the pump 24: takes its supply from said receptacle 2 9, conveying it through the pipe 23 to the pipe 16, and discharges it upon the" chain as hereinbefore described, from which it drips down through the funnel 25 and pipe 27 to return to the receptacle 29. As

thesmoke from the stack 10 through the in- I let conduit,12"usually is in a considerably heated condition, it is obvious that a certain proportion of the water upon the chains willbe evaporated and will pass outwardly through the exhaust port 22. For maintainingg sufficient supply of Water inthe recep- 7 tacle'29 to atall times accomplish the purpose, an inlet pipe 31 from any convenient source: of water supply leads into the auxiliary chamber 32. -Theinle't pipe 31 is cone trolled by a Host valve of any usual and ordinary construction whereby a constant water level is maintained: and a passage 33 forms communication between the auxiliary chamber 32 and the chamber 29 for maintaining the water level in the latter chamber.

The partition which is provided with the passage: 33 prevents agitation in the chamber 29 whichmight be caused by the inflow of water from the inlet pipe 31 so that the water in the chamber 29 is maintained substantially still. p v

For the purposeof discharging the fluid containing soluble chemicals of the receptacle 29 a valved-discharge. pipe 34 is provided. As shown at Figure 1, a pipe 35 is employed simply to carry the exhaust from the pump;2t to the housing where it passes through the housing the same as the smoke from the stack 10.

i 40 but will be a pass through the pipe 27 about the pipe 40 I permitting uncondensed's'moke or fixed gases to rise through this pipe 40 to be again acted It is within the present scope of the in vention and is only necessary that the chains 18 be suspended from nipples 17 which comforming an eye 38 upon. the shank 37 and employing a Wire or rod 39' which may be 'a short wire to operate only independently for each ofthe chain installations ora' rod extending the entire length of the pipe 16 and engaging av number of these eyes 38 uponthe same number of chains. At Figure 4 the wire 39 is shown broken to indicate that it is of indeterminate length and may be as stated merely for securing a single unit in place, or may extend the entire length of the pipe 16, V. I r v It is obvious that the contact of the smoke passing through the inlet pipe 12 and into engagement with the wetted chains 18 and 21 will cool the smoke very rapidly, thereby reducing the volume and aside from the draft caused by the smoke passing out throughxthe exhaust port 22 would produce a draft in the pipe 16.

It is obvious that the water 7 passing, outwardly among the chains and through the chamber will'carry with it some insoluble gases and smoke which will be introduced wlth vthe water into. the receptacle 29'. So that these insoluble onfixed gases may escape," a pipe 40 is located in the pipe 27? and. spaced therefrom: by any approved type of spacers conventionally or diagrammatically shown at Figure 1, it. being. understood that theparti'cular type of spacer is immaterial,

forms a substantially annular passo that it sage between the pipe's 27 and 4E0 through which the water flow into the funnel 25 may 4 pass through the goose-neck 28 to the receptacle. A conical baffle 42' is placed over the top of this pipe 40 so that the drip from the chain will not I diverted into the. funnel 25 to upon by the water or to pass outwardly through the discharge port 22. V L

Throughout the description and in the claims of this application the term water has been used asthe liquid employed for dis solvin the ingredients or wetting the particlesfbut it is to be understoodthat the invention is in-no way limited to the use of pure water or relatively pure water and. that pass into or through the pipe any liquid or solution will be fully within the terms of the present invention, such solution'or liquid depending upon the nature of the products of combustion which enter the apparatus and the materials which it is es-' pecially desirable to extract from such products.

What I claim is:

1. An apparatus for extracting chemical ingredients from smoke comprising a chamber having an inlet opening communicating 'Wltll a smoke flue and an outlet opening lower than the inlet openingya plurality of V chains suspended in the chamber some of i the receptacle to again moisten the chains.

2. An apparatus for extracting the chemi cal ingredients of smoke comprising a chamher having an inlet passage 1n communication with a smoke fine and an outlet port lower than the inlet passage, a plurality of chains suspended vertically from the top of the chamber and covering the inlet passage, nozzles positioned to discharge water uponthe several suspended chains, a receptacle disposed below the chains in position to -receive drip therefrom, a pump communicating at one side with the receptacle and at its opposite side with-the nozzles and adapted to discharge through the nozzles water to maintain an aqueous film upon the chains, and

means to maintain a substantially constant water level in the receptaclel 3. An apparatus for extracting chemical ingredientsfrom smoke comprising a cham ber having a plurality of chains suspended vertically from, the top wall of said chamber, a series of chains below'said first-mentioned chains and disposed at an inclination to the axes of said first-mentioned chains, an inlet conduit communicating with the chamher and covered by the vertical series of chains, an outletstructure including a port communicating with said chamber below said vertical chains, nozzles positioned to discharge water upon thevertical chains, a

. pump for supplying water to the nozzles, a

receptacle positioned to receive the drip from the chains and communicating with the pump, means to maintain a substantially constant water level in the receptacle, and means for discharging the resultantsoluti-on 'from I the receptacle.

In testimony whereof I hereunto atfix my signature.
